Information on the Ebola Virus

Ebola is a severe, often fatal disease, however according to the Centers of of Disease Control (CDC), the actual danger of an outbreak is extraordinarily low.

How does someone become infected with Ebola? According to the CDC, infection can occur when a person comes in direct contact with body fluids of a person who is sick with or has died from Ebola; with objects contaminated with the virus such as needles and medical equipment; or with infected animals such as the blood, fluids or infected meat.

People who are at the highest risk of becoming infected with Ebola include healthcare workers and the family and friends of a person infected. Ebola can only be spread to others after symptoms begin. According to the CDC, symptoms can appear from two to 21 days after exposure. Those symptoms include fever, headache, diarrhea, vomiting, stomach pain, unexplained bleeding or bruising and muscle pain. Diagnosing Ebola in someone who has been infected for only a few days is difficult because the early symptoms are not specific to the infection and are seen in patients with more commonly occurring diseases. The CDC said that if a person has symptoms of Ebola and has had contact with blood or body fluids of a person sick with Ebola, or contact with objects that have been contaminated with infected animals, the patient should be isolated and public health profession-als notified.

What treatments are available to someone infected with Ebola? According to the CDC, there are no specific vaccines or medications that have been proven effective against Ebola and that symptoms are treated as they appear. Timely treatment of Ebola is important but challenging since the disease is difficult to di-agnose clinically in the early stages of infection. The CDC states that experimental treatments have been tested and proven effective in some animals but have not yet been evaluated in humans.

How can Ebola be prevented? According to the CDC, when cases of the disease appear, there is increased risk of transmission within healthcare settings. Healthcare workers must be able to recognize a case of Ebola and be ready to use appropriate infection control measures. Those include isolation of patients with Ebola; wearing protective clothing by those caring for Ebola patients; sterilizing equipment, using disinfectants and avoiding touching the bodies of patients who have died from Ebola. For more information, go to the CDC website at www.CDC.gov.

For Vermont canoeists, kayakers and rafters, there was one last water release along the West River at New England District’s Ball Mountain and Townshend Dams to end a successful and enjoyable summer water season at the projects. Controlled releases were made on Sept. 27 and Sept. 28 to provide desired waterflows for watercraft fun. Approximately 1,300 watersport enthusiasts visited Ball Mountain and Townsend where the fun began at 10 a.m. and continued until 3 p.m. Both projects released water at 1,500 cubic feet per second.

On Sept. 28 water releases began at 10 a.m. and lasted until 3:30 p.m. Both projects released another 1,500 cubic feet per second for 600 small watercraft participants to enjoy. The 8-mile run from Ball Mountain to Townshend Lake has Class I-IV rapids. The two September controlled releases were the third this year. The District performed a water release on Aug. 16.

Ball Mountain, located on the West River in Jamaica, at-tracts 130,000 visitors annually. Other recreational activities include swimming, picnicking, fishing, hunting, nature study and camping at the Winhall Brook Camping Area.

Townshend Dam is located on the West River in Town-shend. Recreational opportunities abound at this site as well. Featured opportunities include swimming, picnicking, fishing, hunting and nature study. Townshend welcomes about 81,000 visitors each year.

Although recreational opportunities are an added bonus, Ball Mountain and Townshend were constructed to keep people safe. Ball Mountain Dam began operating as a flood risk management project in 1961. The 915-foot-long, 265-foot-high structure can hold a 54,600-acre-foot reservoir with a capacity to store up to 17.8 billion gallons of water. Ball Mountain cost $11 million to build and has prevented $16.2 million in damages to date.

Townshend Dam was also built in 1961 and is 1,700-feet-long and 133 feet high. Its lake can hold a 33,700-acre –foot reservoir with a capacity to store 10.8 billion gallons of water. Townshend Dam was constructed at a cost of $7.4 million and has prevented $137 million in damages to date.

Citizen stewardship and volun-teerism are two very important aspects in keeping New England District proj-ects maintained and looking beauti-ful. Although this takes place many times throughout the year, it is most concentrated during National Public Lands Day. Every year a call goes out to local residents asking that they come help celebrate their local public lands by performing cleanup work and improvement projects. Every year the call is answered by hundreds of volunteers who aren’t afraid to get a little dirty.

Several New England District Flood Risk Management projects celebrated National Public Lands Day -- West Hill, Hodges Village and Buffumville Dams in Massachusetts and Black Rock Lake in Connecticut. National Public Lands Day is the na-tion’s single largest volunteer event that focuses on the care and stewardship of all public lands.

Several Girl Scouts and Park Rangers gathered at Black Rock Lake on Sept. 14, to winterize and enhance the native butterfly garden and walking path at the Black Rock Lake in Thomaston, Connecticut.

"This event creates a wonder-ful opportunity to work with the Girl Scouts in order to enhance and preserve our public lands and resources,” said Marissa Wright, NPLD coordinator for Black Rock Lake.

Volunteers rolled up their sleeves at the site to pull weeds, deadhead plantings, and mulch the area.

“The butterfly garden and the field habitat in the area contain na-tive plantings that provide food for butterflies, birds and other wildlife,” said Wright.

The Girl Scouts do an extraor-dinary job each year helping the New England District to maintain the beautiful garden. Black Rock Lake team member Amy Charlton, as well as Wright, assisted the Scouts with the event.

About 183 volunteers came out for the West Hill event, saving the government approximately $24,540.

Buffumville Lake and Hodges Vil-lage Dam once again hosted a large scale event Sept. 27. This year marked Buffumville’s 23rd anniversary hosting a National Public Lands Day event. Ap-proximately 112 District team members and volunteers of all ages turned out to lend a hand in completing all scheduled projects for the day.

Projects included trail blazing and

trash clean-up at Hodges Village; trash cleanup along Oxford Road at Buf-fumville; removing invasive species; painting the main stairs in Buffumville Park; wire brushing and painting grills in the park; Island work- fire pit and mov-ing an outhouse at Buffumville Lake; building/installing privacy enclosure for a port-o-john; replacing stair tread and repairing fences at Buffumville Park. Efforts by participants resulted in a savings of $9,561.20 in labor costs.

Black Rock Lake hosted a Girl Scout Troop that came to do its annual maintenance of the butterfly garden. (See side story.)

According to the National Environ-mental Education Foundation, NPLD began in 1994 with three sites and 700 volunteers. It proved to be a huge success and became a yearly tradition, typically held on the last Saturday in September. Since the first NPLD, the event has grown by leaps and bounds. The Foundation states that in 2013, about 175,000 volunteers worked at 2,237 sites in every state, the District of Columbia, Guam and Puerto Rico.

Firing position structures at the Combat Pistol/MP Qualification Firing Range.

Members of the New England District team, in partnership with the Louisville and Huntsville Districts, as well as the Security Construction and Range Control teams at Fort Devens recently completed two firing ranges at Fort Devens, Massachusetts.

Dave O’Connor, Project Engineer and Chris Caisse, Construction Rep-resentative from the Central Resident Office, joined partner representatives in conducting a joint final inspection of a combat pistol/MP qualifications range at the installation, Aug. 26.

The joint team thoroughly inspect-ed a total of 96 target emplacements, the Control Tower, classroom, storage room, maintenance area, covered mess, bleachers and ammunition sup-ply building as well as all of the circuitry. “Each of the 96 target emplacements sit on a mound of earth and has complex data and power wiring for the targets,”

said James Morocco, Chief of the Cen-tral Resident Office. “The inspection goes over every emplacement and

structure.”During the early stages of construc-

tion, the joint team conducted an initial

inspection to ensure that the position of the first installed tar-get emplacements and wiring was cor-rect and compatible so that the rest of the emplacements could be installed.

The New Eng-land District Team of O’Connor and Caisse made daily inspections of the project as work was ongoing, so it was no surprise that it passed the final, joint inspection.

“Usually, an in-spection like this takes a full day, but because the project was in top shape, the inspection did not take as long,” said Morocco. “This particular team has completed over 100 range inspections this year and they stated that this range is rated in the top two, if not the best they have seen.”

Construction on this $3.6 million project began in March and was com-pleted in September. Security Con-struction of Hudson, Massachusetts, an 8A contractor, performed the work for the New England District. Now that the range has passed inspection, Fort Devens personnel can proceed with installing targets and training Soldiers.

In addition to the combat pistol/MP qualifications range, the District com-pleted a $2.1 million Known Distance (K-D) Range at Fort Devens, passing its final inspection on time and within budget. Construction on the project began in March and was completed in late August.

This project provides the Army and Marines with a 60-lane, multi-use facility that extends to 600 meters at the lon-gest distance. New England District’s

Nick Skianes, Project Engineer, and Chris Caisse, Construction Represen-tative, oversaw the construction and the daily inspections. Tantara, an 8A, Hubzone Woman-owned business from Worcester, Massachusetts, performed the work for the District. “This is one of the rare times that we had a Design/Build project with an 8A contractor,” said Morocco.

The Known Distance range is much different from the combat pistol range. “There is a platform at the far end of the range that is about 8-feet below the level of the shooters,” said Morocco. “The targets are on a lift that raises and lowers them. The targets are graded and loaded manually, so there is a person sitting below the target when the person above is shooting.”

According to Morocco, there is a canopy for shrapnel that protects the operator. Previously, the targets were lifted by hand, but technology has advanced and the District installed electronic lifters for this project.

Because the range will be used jointly by the Army and Marines, the

District built multiple firing points in yards for the Army and in meters for the Marines. “We have a 100-meter shooting spot as well as a 100-yard shooting spot for each shooting position up to the 600-meters,” said Morocco.

The New England District has completed three firing ranges for Fort Devens this year alone, making the total firing ranges constructed on the installation at seven. The District will partner with Louisville and Huntsville once again to construct another range in the near future.

“While many people believe that Fort Devens is closed, there is an active Army Reserve containment area as well as nearly 5,000 acres of training area,” said Morocco. “This training area hosts an average of 135,000 people annually including military, federal agencies such as the FBI, CIA, DEA, Secret Service and Homeland Security as well as numerous local police departments.”

Assisting Fort Devens by construct-ing these firing range facilities is in keeping with the USACE Campaign Plan initiative, “Support the Warfighter.”

The Federal Women’s Program and the Equal Employ-ment Opportunity Office hosted a Women’s Equality day Celebration, Aug. 26.

Denise Kammerer-Cody, FWP Manager, thanked ev-eryone for attending and introduced the keynote speaker. Local performer Sally Matson served as the presenter for the event, per-forming “Margaret Bourke-White…Courageous Pho-tographer.”

Matson, dressed in period clothes, told Bourke-White’s adventures climb-ing on skyscrapers, leaning out of airplanes and going into war zones. Born in 1904 in the Bronx, New York, to an engineer father and an educated home-maker mother, Bourke-White originally wanted to be a scientist, studying Herpetology, Paleontology and zoology as well as art, swimming and aesthetic dancing at about seven colleges throughout her academic career.

She started to take pictures of the Cornell University Campus as a way to make money, then her career quickly blossomed into industrial photography. Her first cover was Life Magazine, but her first magazine photo came from Fortune. Fortune quickly became one of the leading photographic magazines thanks to Bourke-White, and she gained much recognition in the process.

During her career Bourke-White photographed iconic buildings such as the Chrysler Building and became the first foreign photographer to have unlimited access to the Soviet Union. In 1936 she was recognized as one of the 10 most notable women of her time. While in the Soviet Union, Bourke-White began photographing people instead of buildings. She traveled all over the world and photographed many famous people. One of her most notable photos was of Mohandas Gandhi in 1946. Other people Bourke-White photographed were Franklin D. Roosevelt, Winston Churchill, and Pope Pius XII.

Bourke-White traveled all over the world, photographing images during World War II and the Korean War. She pio-

neered quality photojournalism and the photo essay. She also published 11 books before her death from Parkinson’s Disease in 1971.

After Matson’s performance, Lt. Col. Charles Gray, Deputy District Command-er, presented her with a Bunker Hill plaque in ap-preciation for her coming to the District.

President Barack Obama issued a procla-mation in recognition of Women’s Equality Day stating, “On August 26, 1920, the 19th Amendment was certified, securing for women the fundamental right to vote. The product of decades spent organizing, protesting, and agitating, it was a turning point on the long march toward equal-ity for all, and it inspired generations of courageous women who took up this unfinished struggle in their

own time. On the anniversary of this civil rights milestone, we honor the character and perseverance of America’s women and all those who work to make the same rights and opportunities possible for our daughters and sons.”

Travel lane restrictions on the Cape Cod Canal’s Saga-more Bridge in Bourne, Mass., began Sept. 22, as the team works to complete the $12.3 million bridge painting project, according to U.S. Army Corps of Engineers, New England District officials.

Lane restrictions will be temporary and will avoid dates of peak traffic volume. The plan is to take only one lane daily during 8 a.m. to 4:30 p.m. and leave open one lane going on Cape and two lanes going off Cape. Lane restrictions will be a daily set-up of traffic control devices during daylight hours only. All travel lanes will be open each night and on weekends. This schedule will last three weeks.

Then, after Columbus Day, starting on Tuesday, Oct. 14, Sagamore Bridge travel lanes will be restricted to ONE LANE IN EACH DIRECTION – one lane going on Cape and one lane going off Cape daily during 8 a.m. to 4:30 p.m. Additionally, lane closures may be possible on weekends, if needed by the contractor team to complete the bridge work. Workers will begin to dismantle and remove the access platforms and the containment system that were needed on

the bridge painting project. This schedule will last to about the end of December when work and cleanup are scheduled to be completed. Motorists should consider avoiding peak travel periods or seeking alternate routes to avoid delays.

During the lane restrictions, no wide loads will be permit-ted to cross the span, and state and local police will be on duty to assist the motoring public. This bridge work is critical to maintaining the structural integrity of the bridge, which is a vital component to the transportation system of the Cape, the Islands and southeastern Massachusetts.

Message boards and bridge work alert e-mails are used to help inform motorists of pending lane restrictions and bridge work. To sign up for bridge work alert e-mails send an e-mail to CapeCodCanalBridges@usace.army.mil with the subject “Bridge Work Alerts.” An e-mail alert is sent when there is a major change to the bridge work status or schedule. The Cape Cod Canal website is http://www.nae.usace.army.mil/Missions/Recreation/CapeCodCanal.aspx.

Additionally, updates are available from the Corps’ New England District via Facebook and Twitter: on Facebook: http://www.facebook.com/CorpsNewEngland; on Twitter: http://twitter.com/CorpsNewEngland.
